raidian (arknights)

Raidian is a Supporter Operator in Arknights, a Liberi whose real name is Serafina Petrova, an analytical specialist who prefers calculated observation over direct confrontation. Her art presents her with short white hair, a halo-like circlet floating above her head and a crisp, tailored outfit with technical gear, gloves and a long coat. Her expression is usually cool and detached.
